    • The invention relates to a process for the avoidance of burrs when demoulding the reconstructed stone and decorative panels, as well as the finished products - reconstructed stones and decorative panels without burrs - obtained through this process. According to the invention, the process comprises the following steps: Step 1, selecting the type of reconstructed stone or decorative panel to be multiplied; Step 2, the assembly of natural stone slabs to a suitable size so that they can be manipulated - for example maximum 1m / 1m - so that, on one side, the surface with the desired pattern is obtained; Step 3, impregnating the surface with the desired pattern in a plastic mass that can take in depth the strips, the grooves, etc. specific to the natural stone - for example silicone rubber - in order to obtain the negative mould 1] Step 4, in the negative mould 1, a plastic mass different from that of the negative mould 1 is poured, with the same rendering qualities of the surface pattern on which it is poured, resulting one or more positive moulds 1 (fig. 1), which render/reproduce almost identically the surface of the natural stone slabs; the edges are bevelled from the inside, on the contour, about 2 - 10 mm x 45°; Step 5, with the positive mould 1, is impregnated at a certain temperature, a plastic mass of the same material as that of the negative mould 1, or another plastic mass having similar qualities to it, in order to obtain one or more negative moulds 2 (fig. 2), having a thickness between 10 - 100 mm; between the negative moulds 2 there are 10-50 mm decks which, on the contour, have an inner shoulder of 2 - 10 mm x 45° (fig.3). Step 6 in the negative mould/moulds 2 there will be poured the mixture of cement, plaster, etc., which is pressed with a press whose entire surface (of contact with the cement or plaster mixture) is substantially porous; by reinforcing the mixture, identical reconstructed stone tiles (fig. 4), and identical decorative panel tiles are obtained, which will have; a) a previous conventional surface, with the pattern, reproduced of natural stone; b) a significantly porous rear conventional surface that is placed on the wall and comes into contact with the binder; c) a finely processed contour surface by casting; d) the chamfering of 2 - 10 mm x 45° on the contour at the edge between the finely processed contour surface and the conventional porous rear surface. Due to the elasticity of the material of the negative mould/moulds 2, the slabs will be easily removed from the mould, without this/these deforming, or breaking; Step 7, control, packaging of finished parts and storage. By carrying out the process, finished products are obtained - reconstructed stone and decorative panel - without burrs, directly by casting and drying, having the edges between the contour surfaces and the conventional rear surface evenly bevelled and along the entire contour of the part, resulting, on the one hand, the increased degree of adhesion of the reconstructed stone slabs and the decorative panel slabs on the wall, mural, etc., because the soldering material (plaster) also enters the joints of the recessed edges, and on the other hand, the execution of the finished parts is considerably reduced, resulting in a cost per unit of processed part decreased accordingly.
